i i inois. have invented a certain new and use il Improvement in Shock-Absorbers, ofh the following is a full, clear, concise, lIeIXact description, reference being had to I "ccompanying drawings, forming a part nsspecifioation. I

rnother object 'ofthe invention is to pro-I I a shock absorber more particularly ii l tedgfor vehicles such' as automobiles ant which employs a frictional. arrangement i 20`adapted to act inbothdirections.

'I I 1I The invention furthermore consists in the IIiinprIm'e/men'ts `in the parts and devices and thenovel coinbinationsnof theparts 'and fines,I `as herein shown, described or 251 claimed. I I I .I Tnthedravving forming a part of this ''.cation, Figure 1 `is a side elevation of portion offen automobile chassis and I gs, `Withmy improved shock absorber "ched thereto,- the `raxle *being shown in on.

flange 17 is cut away as indicated at 19-19 to thereby provide a seat for a cover or side plate 20.` Atthe sides, the iange '17" isprovided with offset portions 21-21 in which are arranged to be seated springs 22-22, the 60 latter having their ends seated against-'the shoulders 2323 formed by the offsets 21.

The inner side of the circular flange 17 at the top and bottom thereof forms friction surfaces 24 with which coperate friction 65 shoes 25, each of said shoes 25Ihaving shoul-v the endsof 'the springs 22. Each of said I surfaces 27 The rear Wall 16 and the cover plate 20 are provided with circular holes 28-28 through which extend bosses 29,-29 formed on the opposite sides of a WedgeSOIIWhich 75 Wedge isprovided at the top and bottom thereof with a Vpair of oppositely arranged l Wedge acting faces 31--31. Anti-friction rollers 32--32 are interposed between the Wedge acting faces 31 of the Wedge and the 8G wedge faces 27 formed on the innersides of the jfriction shoes Each boss. or lateral 'extension 2 9 has upper and lower abutinent's` 52--52,`eachA abutment .52 having a pairof oppositely arranged shoulders 33. For os- 85 cillating the Wedge, a pair oflever arms '34 I' are provided on opposite sides of the casting cesses 35 ")eing provided Withsets of'shQill- .I I

ders 36 6 which are normally spaced fr pm the shoul ers 33 as indicated most clearly in Fig. 2. The lever arms 34-,arejho'1lowed out to receive adjustable extensions 37, the latter 95 being held in place .by `set screws BBIwPivotally connected to the, extensions 37 isia link 39 which4 is pvotally' attached to 'the charsis I e lever arms 34; are held in place by means 015.160 a bolt 42 and nut 43 thereon, which bolt is,y extended 1 through suitable perforations in l said arms'and a central hole thrdlihthe Wedge 30.-

' The operation of the deviceis aslfolqvisz' When the chassis moves toward the axle 11, the lever arms 34 will be' oscillated down; Wardly but during the first portion of this" movement the Wed'ge() will not'be acted .upon inasmuch as the lever arms 34: are free :uw:

to move 'independently of the wedge an amount corresponding to theA normal space between the shoulders .36 and shoulders 'greater than an inch, it is apparent thatthe wedge ltl will be oscillated clockwise as viewed in l] thus causing the antifrictwn rollers 32 to belwedged between two ofeoperating edge faces 3l and 27 This action will increase 'theipresfmre' between the friction surfaces ofifthe friction shoes and the inner face of the. circular flange 17 y and circumferential movement of the fricvtion shoes-ill be yieldingly resisted by the sliringas 22, 'one end of each spring :beingl engaged b v a friction, shoe and the other ond ofthmsprmgbeing held by afshoulder 23; Similarly, on the-recoil or'separation sorberconics into play after the Chassis and axle have separated more than the'perdetermined amount, namely, an inch 1n preferable construction.- The action of the shock absorber on the recoil lsf. the same as previonsly described except in the reverse direc-- tion.

lFrom the "preceding description itwill` 'be seen that theshock absorber isfexceedl" ingly compact and can be applied 'to practically allltvvpes of automobiles andthe alfi rangement is such that by varying the Aspace Ibetween the shoulders 33 and 3,6, the shock absorber maybe brought into' play at .any

. desired time although preferably nthede- .sign is' such that with a `normal load, the

cl'iasfs'is may movenp or down one inch'rela tivelyto the axle withoutactnatirngthe friction elements, further movement 'in either direction oi'ierating'the friction velementsas hercinljicfore,described. ,Y
